Sodium carbonate, Na2CO3, reacts with hydrochloric acid, HCl, to produce sodium chloride, carbon dioxide and water. Refer to slide 7.18 for a summary of formulae relevant to the calculations below. 2HCl(aq) + Na.CO3(aq) + NaCl(aq) + H2O(l) + CO2(g) 1. Use this reaction to explain what is meant by the terms "acid", "conjugate base" and "salt" 2. Balance the equation for this reaction. 3. A solution was prepared by dissolving 5.00 g of Na2CO3 in water and adding water to...
The Na,Co, solution described above was used to analyse a hydrochloric acid solution of unknown concentration. It was found that 24.30 mL of the Na,Co, solution was required to neutralise a 20.00 mL sample of the hydrochloric acid solution. 4. Using your answer to part 3 above, calculate the amount of Na,Co, present in 24.30 mL of the Na,Co, solution. (2 marks) 5. Using your answer to part 2 above, deduce the amount of HCl that was present in the...
Solubility product constant of calcium iodate/common ion effect. I am unsure how to do this however I am only asking for help on trial one as there are 4 total trials and I would like to be able to do those on my own after I have learned how to do the work. Thanks. Also, could you provide the balanced equation for the titration as well as the solubility equation for iodate? Part A: Saturated Calcium lodate-No Added Calcium lon...

Biochemistry problem! Next determine the recipe for making a buffer by mixing stock solutions of a buffer molecule (base form) and hydrochloric acid. The concentrations of the buffer (base) and HCl solutions are provided by the web page. Calculate the volume (in mL) needed to make a buffer with the same pH and concentration as in Question #1. Assume that water will be added to bring the volume up to the assigned total volume. Use the web page to check...
Sodium hydroxide, NaOH, solutions can be used to acids such as hydorchloric acid, HCl: A 0.500 M NaOH solution is used to titrate several aliquots of 25.00 mL of an unknown concentration of HCl. Use the data in the table below to determine the average concentration of the hydrochloric acid solution (starting before the titration) and the standard deviation. Trial # Volume NaOH (mL) Trial # Volume NaOH (mL) 1 16.01 6 15.84 2 15.54 7 15.89 3. 15.71 8...
How could you make 2.5 L of 0.10 M hydrochloric acid? Question 10 (1 point) How could you make 2.5 L of 0.10 M hydrochloric acid? Hint: This is a dilution. How many moles of HCI in 2.5L of 0.1M? Use the fact that M = ? that M - n moles so # of moles n = M, V =.. O dilute 59.4 mL of 3.0 M HCl to 2.5 L with water O dilute 0.25 L of pure...
Worksheet 2 2. Calculate the concentration of each of the following solutions. Determine the molarity (mol/L) of a solution made by diluting 5.880 g of barium chloride to a final volume of 525.0 mL a. b. What is the molarity of a solution that dilutes 12.50 mL of 6.00 M HCI (hydrochloric acid) to a final volume of 1.50 L? If you combine 1.55 g of NH CI (ammonium chloride) with 2.38 g of CaCl, (calcium chlo- ride) and dilute...
